About halfway through season seven, episode three, "The Queen's Justice," Jon Snow and Tyrion Lannister have a heart to heart after Snow's initial meeting with Dany got off to a bit of a rocky start. Unsurprisingly, she wasn't convinced when Jon told her there's a giant undead army coming to kill everyone in Westeros.

Naturally, it was the perfect opportunity for Tyrion to poke some fun at the undead, but we didn't expect to hear what he said.

If you missed the moment, head back to 35 minutes into the episode. Here's the exchange between the two:

Jon: "The dead are coming for us all." Tyrion: "Why don't you figure out what to do about my missing fleet and murdered allies, and I'll figure out what to do about your walking dead men."

Oh, Tyrion. HBO, INSIDER composite

Yes, "Game of Thrones" made a mention of AMC's "The Walking Dead." Of course, fans spotted it immediately and they had quite the time with it.

A lot of people were actually excited by the thought of the two shows coming together, if only for a moment.

Others thought HBO may have been taking a small shot at AMC's popular series, which also airs on Sunday nights, but in the fall and winter months.

"I love the idea of skeletons walking around — that they threw themselves off a cliff and get up and then just start running. I thought it was great," Nicotero told INSIDER last April of the season five episode "Hardhome" where Jon Snow and the wildlings face an army of wights.

"Skeletons crawling around and killing people is awesome," he added. "That supernatural aspect of that makes them, by nature, very different than ours."

The next episode of "Game of Thrones" will air August 6. "The Walking Dead" will return to AMC October 22. And, you know what, maybe Rick Grimes could use a man like Tyrion on his side.
